Spread protein intake across all three meals, calibrated to body weight

Morning protein helps middle-aged adults build and preserve muscle

"I want to try the 'natural Wegovy' diet, but I have no idea how many eggs I should be eating in the morning." — a woman in her 40s

A trend dubbed the "natural Wegovy" diet — eggs drizzled with olive oil — has prompted more people to make eggs a regular part of their morning meal.

The "natural Wegovy" diet refers to an eating pattern designed to mimic the effects of GLP-1 (glucagon-like peptide-1) class drugs through food alone. The combination of a protein source (eggs) and healthy fat (olive oil) is meant to stimulate the body's natural release of GLP-1, a hormone that helps regulate blood sugar and prolong feelings of fullness.

The diet is particularly well-suited to middle-aged adults, for whom adequate protein intake is especially important. As the body ages, maintaining muscle mass and a healthy weight requires deliberate effort.

Nutritionists say breakfast is an ideal time to get that protein in. People tend to load up on protein at lunch or dinner, but experts advise spreading intake evenly across meals for more effective muscle synthesis. Boosting morning protein can give middle-aged adults a meaningful edge in building and preserving muscle.

The underlying principle is straightforward. When protein synthesis outpaces breakdown, muscle grows; when breakdown dominates, muscle is lost. Skimping on protein at any meal tips the balance toward breakdown, because — unlike fat or carbohydrates — the body cannot store protein as a reserve. The spike in muscle protein synthesis that follows a meal returns to baseline within a few hours.

A clinical trial by researchers at the University of Texas Medical Branch, published in the Journal of Nutrition in 2014, confirmed this. Participants who spread their protein intake evenly — 30 grams at each of three meals — showed muscle protein synthesis rates 25 percent higher than those who concentrated their intake at dinner (10 grams at breakfast, 15 grams at lunch and 65 grams at dinner).

According to the Ministry of Health and Welfare's 2025 Korean Dietary Reference Intakes, the recommended daily protein intake for a typical adult is about 0.9 grams per kilogram of body weight. For a woman weighing 55 kilograms, that works out to roughly 50 grams a day — or about 17 grams per meal when divided evenly across three meals.

To hit that 17-gram target at breakfast with boiled eggs alone, about three eggs would do the job. According to nutritional data from the Ministry of Food and Drug Safety, 100 grams of hard-boiled egg contains approximately 13.5 grams of protein — roughly 6 to 7 grams per egg at 50 grams each.

When eating eggs in the morning, soft-boiled or fried eggs are easier to digest than hard-boiled or oven-roasted varieties. Protein is made up of amino acid chains, and moderate heat breaks down that structure enough for efficient digestion — too much cooking can work against it.

Fish is another good option. Low-fat, high-protein varieties such as dried pollack or cod fillet are light enough to work well as a morning meal.

For the 55-kilogram woman in the earlier example, a single cod fillet would be enough to meet the 17-gram morning protein target — or even half of a large fillet.

One common mistake to avoid when calculating protein intake by body weight: the relevant figure is the protein content of a food, not the food's total weight. Eating 50 grams of beef, for instance, does not mean consuming 50 grams of protein.
